Human Leptin/OB Antibody Summary

Species Reactivity
Human
Specificity
Captures human Leptin/OB in sandwich ELISAs. In this format, this antibody shows less than 0.1% cross-reactivity with recombinant mouse (rm) Leptin/OB and rrLeptin/OB.
Source
Monoclonal Mouse IgG1 Clone # 44802
Purification
Protein A or G purified from hybridoma culture supernatant
Immunogen
E. coli-derived recombinant human Leptin/OB
Val22-Cys167
Accession # P41159
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.

Applications

Recommended Concentration
Sample

Human Leptin/OB Sandwich Immunoassay

Recommended Concentration
Reagent
ELISA Capture (Matched Antibody Pair)
2-8 µg/mL 

Use in combination with:

Detection Reagent: Human Leptin/OB Biotinylated Antibody (Catalog # BAM398)

Standard: Recombinant Human Leptin Protein, CF (Catalog # 398-LP)

Neutralization
Measured by its ability to neutralize Leptin/OB-induced proliferation in the BaF3 mouse pro‑B cell line transfected with human Leptin R. The Neutralization Dose (ND50) is typically 0.4-1.6 µg/mL in the presence of 7.5 ng/mL Recombinant Human Leptin/OB.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Cell Proliferation Induced by Leptin/OB and Neutralization by Human Leptin/OB Antibody. Recombinant Human Leptin/OB (Catalog # 398-LP) stimulates proliferation in the BaF3 mouse pro‑B cell line transfected with human Leptin R in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human Leptin/OB (7.5 ng/mL) is neutralized (green line) by increasing concentrations of Human Leptin/OB Monoclonal Antibody (Catalog # MAB398). The ND50 is typically 0.4-1.6 µg/mL.

Preparation and Storage

Reconstitution
Reconstitute at 0.5 mg/mL in sterile PBS.

Background: Leptin/OB

Leptin is a protein product of the mouse obese gene. Mice with mutations in the obese gene that block the sythesis of Leptin have been found to be obese, diabetic and to have reduced activity, metabolism and body temperature. cDNA clones encoding Leptin have been isolated from human, simian, mouse and rat cells. Human Leptin shares approximately 84% sequence identity with the mouse protein. Human Leptin cDNA encodes a 167 amino acid residue protein with a 21 amino acid residue signal sequence that is cleaved to yield the 146 amino acid residue mature protein. The expression of Leptin mRNA has been shown to be restricted to adipose tissue.

A high-affinity receptor for Leptin (OB-R) with homology to gp130 and the G-CSF receptor has been cloned. OB-R mRNA has been shown to be expressed in the choroid plexus and in the hypothalamus. OB-R has also been identified as an isoform of B219, a sequence that is expressed in at least four isoforms in very primitive hematopoietic cell populations and in a variety of lymphohematopoietic cell lines (1-3). The roles of leptin in body weight regulation, hematopoiesis and reproduction continue to be investigated.
